course, forming the divide between
Concomelly and LouplDup creeks.
| The lowest gap on this ridge Is near
! ly opposite the northernly end uf
Ruby toWnsite. Up through this
gap 4 rough and very steep pack
trail Is made, making Il rise of 1860
feet In a mile anda half. This, at
: present, Is The only line of access to
the principal mines, which are Sit
uated. In most part, along the south
west flank OF the mountain and tX.
tending south from the gap Il dis.
,ance of about two miles. The
water supply on this mountain ridge
Is limited to few small springs dur.
ing the dry season, and only suffici-
ent for domestic purposes. ! found
no supply Of water on the mountains
sufficient for reduction works of any
considerable extent. TO get a sufiici.
ent supply ot water Mt all seasons OF
the year for extensive reduction
works, the ores must be conveyed
by wire tramway through tho gap
above mentioned, called Ruby canon
to the Concomelly creek above the
townste. AT this point there Is nm
admirable location for reduction
works of sufficient extent to handle
all the ores OF the entire district. A
| wire tramway properly constructed
from the milsite up through Ruby
canyon gap, and along the west flank
of Ruby mountain below the mines,
will make the best and cheapest
mode of conveyance for the ores OF
! the district to the reduction works
Each important mine could have q
light wire tramway, or, In some
cases, II wagon road, from the mine

tion on the main line, thus enabling
them to send their ores to the re-
ductlOn works at all seasons of the
year.
The country rock OF Ruby district
is, in most part, granite, gneiss, mica
and hOrnblend schists, all presenting
Il cOarsely bedded structure, uplifted
or folded to nearly vertical positions,
having a general trend from north
west to southeast, and dip northeast,
at angles varying from 60 degrees to
nearly vertical. These bedding lines
OF the granite schists cut through the
mountain on very o5lique angles,
say 10 to 20 degrees. The longi.
tudinal axis of the ride being fifteen
to twenty degrees more sOuthernly
than the course Of the bedding planes
of the country rock.
The greneral aspect Of the country
rock Is coarse feldspathic granite,
with alternating bands of horn blcu.
die and micaceous schists of coarse
granite structure. The formation i.
evidently of primordial type pro.
bably belonging To the Archian So
ries.
The width Of this zone OF gnelssOid
GRANTEES and chists Is at least two or
three miles. hanked on the south
west side by massive GRANTEES OF
great extept, rising into high noun
tain ranges at the west.
The mineral belt of zone, 80 far as
known In Ruby district Is two or
three miles wide, and Is confined To
the granite bedded formations above
described. BY far the largest
the district are substantially con-
fermable to the dip and strike OF the
schistose rocks, having II general
coarse nearly southeast to northwest
magnetic and dip (northeasD vary
ing from fifty degrees to nearly
vertical positions. While the general
strike and dip of the bedding struc-
lures OF the country rock hold their
course as stated, the local variations
are very numerous, both "a to strike
and dip.
There are two or three lodes In the
district that have course nearly
north and sOurh, and dip east at high
angles. varying from sixty to eighty
degrees below the horizontal plane.
These cut through the bedded for
nations obliquely at angles varying
from thirty to fifty degrees, thus
marking them distinctly as true
assure lodes." The most prominent
of these Ms fissure lodes is tho
darlington Lode" in the sOutherly
end OF the Ruby mountain group OF
mines. q donot mean by the lOdes
that a.'e conformable to the dip aud
, strike of the country rock are not
iissure lodes also. Think all the
! principal lOdes of the district are
fissure lodes. ! arrive at this con.
clusiOn from facts not necessary to-
state in this connectOn.)
The Arlington mine Is situated as
above stated, in the southerly end OF
the Ruby mountain group Of mines,
on the west side and about 800 feet
vertically below the apex OF the
mountain ridge.
Its course Is about north and south
cutting through the granitic chis,s
and gneissoid rock at 0blique angles,
as above described.

angles varying from 80 to 80 degrees
below the HORIZONTAL plane or am

grees from the vertical plane.
The "width"o of the lode between
It's walls is variable $50 far as the sur
